Address any kind of math concept or problem with a series of problem-solving strategies. Over 12 days of different activities and increasing skills, learners practice different ways to solve problems, check their answers, and reflect...

Show learners how to apply rational equations to the real world. Learners solve problems such as those involving averages and dilution. They write equations to model the situation and then solve them to answer the question — great...

Show the class two methods to solve proportions of fractions. The instructor shows that complex proportions can be solved by the normal method of cross-multiplying. It also shows another method where the complex fractions are simplified...

Given problem situations involving similar figures, the student will use ratios to solve the problems.

Cross multiply and solve for the unknown variable in this proportion problem. Then use the division property of equality to isolate that variable and get your solution.

Multiple discounts are always a good thing. Viewers of an informative video see how to calculate sale prices by applying multiple percent discounts. They also learn to determine the resulting total percent discount by multiplying ratios.

Find out if the amount of practice is proportional to better test scores. The video explains the steps learners perform to solve a proportion. Supplemental videos show examples of solving proportions of varying difficulty, which helps...

Take an indirect view of proportionality. Using a similar approach of direct variation, the resource shows how to solve inverse proportions. The video steps through finding the constant of proportionality to write the formula for the...

Know how to solve problems with one ratio? Then solving problems with two ratios will be a cinch. Pupils watch an engaging video to learn how to solve problems involving two ratios. It first shows the method of combining the ratios into...

Solve a proportion where the variable is the numerator of one of the fractions. How? Just use the multiplication property of equality. This means multiply both sides by the reciprocal value of the denominator. Then the variable will be...
